Airbnb listings with descriptions over 2,000 characters earn 70% more annual revenue than listings under 200 characters.
That's from a new analysis by Jeff Brown at IntelliHost, who looked at over 15,600 active 2-bedroom listings and compared description length to revenue. Conventional wisdom says to keep the descriptions short and sweet (because people have short attention spans, right?), but the data says the opposite.

Here's the data:
And the "2,000+ characters" group is the biggest group in the sample, so a lot of high-performing hosts are writing long descriptions.
What might be driving this
Before you rush to pad your listing with filler text, it's worth thinking about why long descriptions outperform. Here's a few thoughts:
Operator sophistication
The kind of host who writes a detailed, thoughtful description is also the kind who has professional photos, dynamic pricing, and good guest communication. So longer descriptions are naturally aligned with someone who takes managing Airbnb seriously.
Guest filtering
A guest who reads a long description and still books is more intentional than one who books based off a cover photo. Plus, the longer description answers some of their pre-booking questions, so the guest is making an educated decision. That filters out a lot of the problem bookings that can drag down reviews and revenue.
Search visibility
More text gives Airbnb's algorithm more to work with when it's matching your listing to guest searches. More text = more keywords about what your place actually offers for the algorithm to pick up on. That can turn into more impressions and more bookings.
What the study doesn't control for
The study filtered for 2-bedroom Airbnb listings with 10+ reviews and $10K+ annual revenue, which rules out the obvious part-time listings. But it doesn't factor in location or rate tier. Essentially, if premium oceanfront properties also tend to write longer descriptions, that could skew the data.
Worth the 20 minutes
Taking all of this into account… Even if a longer description is only a little bit linked to more revenue, it's still the easiest lever to pull.
It takes less than 20 minutes to rewrite a listing description, and it could have a big payoff. So it's at least worth looking into. It could be a simple improvement hiding in plain sight.
